Ferrari SF90 Stradale is first series production plug-in hybrid electric vehicle in Ferrari history
The Ferrari SF90 Stradale is now in Malaysia. The supercar is the first plug-in hybrid series production vehicle in Ferrari history and has all-wheel drive.
Technological innovations introduced in the SF90 Stradale include the all-new aluminium and carbon fibre chassis, an all-carbon-fibre bulkhead between the cabin and the engine and the use of two new aluminium alloys. The SF90 Stradale chassis has 20% higher bending stiffness and 40% higher torsional rigidity than previous platforms without any increase in weight. This has significant advantages for the car’s dynamics. There is also a new alloy known as ‘quiet aluminium’ for the floor pan which reduces NVH (noise, vibration, harshness).
The steering wheel with a touchpad for controlling car functions using the thumb and digital central instrument cluster with 16-inch curved HD screen are new features, appearing for the first time in a Ferrari.
The SF90 Stradale has the same internal combustion engine as the F8 Tributo but output has been increased from 3902cc to 3990cc by increasing the bore to 88mm. The V8 produces 768bhp, boosted to a combined total of 986bhp by three electric motors. The additional power helps to compensate for the additional 270kg from the hybrid system. 100km/h takes 2.5 seconds and 200km/h in 6.7, making the SF90 Stradale Ferrari’s fastest car.
There are two motors at the front wheels, which operate independently of each other, while the third is at the rear between the engine and gearbox. Each motor driver has its own inverter to manage AC and DC charging to the 7.9 kWh lithium-ion battery. There is also regenerative braking, enabling a total electric range of 26km. The transmission is an eight-speed dual-clutch. There is no reverse gear – the two motors at the front wheels provide torque vectoring or RAC-e (rotation axis control electric) which also enables the car to move in reverse.
There are four driving modes with an all-electric mode, eDrive. Hybrid mode, the default mode, is a combination of engine and electric motors, switching to all-electric mode to save fuel if conditions permit. Performance mode is primarily the engine, in order to charge the batteries. In Qualify mode, the electric output is prioritised to provide maximum performance.
A new electronic Side Slip Control system was developed to integrate the control logics required by the new hybrid and ensure the high-voltage system controls (battery, RAC-e, MGUK, inverter), engine and gearbox control and vehicle dynamics controls (traction, braking, Torque Vectoring) and the existing vehicle control logics could work together. The new eSSC introduces three new features for distributing engine torque to the wheels:
- Electric Traction Control (eTC) which manages the torque availability to the individual wheels
- brake-by-wire control with ABS/EBD to distribute braking load between the hydraulic and electric motors to minimise brake fade and improve brake feel
- torque vectoring to maximise traction and stability when cornering
The SF90 Stradale’s aerodynamics have been optimised and it is able to generate 390kg of downforce at 250 km/h, the highest amongst its peers.

Two versions of the SF90 Stradale are offered: a standard car and a sports-oriented, Assetto Fiorano specification which comes with GT racing-derived Multimatic shock absorbers, carbon-fibre door panels and underbody, titanium springs and exhaust line) which shave 30 kg off the total weight. The Assetto Fiorano also has a high downforce carbon-fibre rear spoiler which generates 390 kg of downforce at 250 km/h, and Michelin Pilot Sport Cup2 tyres designed specifically to improve performance on the track in the dry. They are made of a softer compound and have fewer grooves than the tyres provided as standard.
The Ferrari SF90 Stradale is available from the base price of RM 1,908,000.00 (before duties, customisation options, taxes and insurance). For further details, contact Ferrari Malaysia.
